Are the plain (unpainted) Terra Cotta pots you find at craft stores safe to put in a fishtank? I ask because I want to give my Betta a hiding spot, but with the way the plants are in his tank I currently don't have anything small enough. The mug I had is too big for the available space. I got to thinking about those small Terra Cotta pots, but I didn't know if it would be safe. I mean, does the Terra Cotta degrade under water? Or would it be OK?

Most people on this forum use those pots. I for one am a huge fan of them, have no idea why though, i just think they look cool haha. The pots are safe to use just make sure you wash throughly before you add it to your tank
